Thanks to all I've read here, I have settled on the 4.10's. But I don't know exactly what parts I need to switch over the gears. Is it just the ring and pinion, or are there other parts involved. I have a 05 GT, 5sp with 1500 miles on it. I appreciate any help.

 

essentially that is all you need plus an installation set. i wouldn't expect to do it myself though. setup is/can be complicated to ensure durability and quietness.

 

Thanks! Yeah, I know enough to stay away from this job.

 

i'd expect you can get richmond gears installed under $400.
